Yes, there is at least one limitation: there is a 64k block limit on TFTP due to the 16 bit block number field. This gives a maximum NBI size of 16 MB or 32 MB depending on whether the field is treated as signed or unsigned (should be unsigned, but there is buggy code out there). While I think Etherboot can handle the rollover (it has never really been tested), many tftpd's cannot. You can mitigate this by using the large block size option with tftp giving you 64k * 1.5kB = about 90 MB, so I think you can just make it. You'll probably need to use the tftpd distributed as source provided with Etherboot. I don't know if NFS booting (also supported in Etherboot) would help. =========================================================================== This Mail was sent to netboot mailing list by: Ken Yap <firstname.lastname@example.org> To get help about this list, send a mail with 'help' as the only string in it's body to email@example.com.
